  I agree, but I actually like the idea of using config.cache.  This
would alleviate us from coming up with our own pkgautoreconf (and
eventually getting into the same mess we were in with pkglibtool).

  It should be rather easy to produce a "default-deny" config.cache
using a script that just scans the GNU "configure" script and adds the
desired "ac_cv_lib_whatever_main=no"/"ac_cv_header_whatever_h=no"
entries to "config.cache".
